It was also introduced to southern China and India by Austronesian traders around 1200 to 1000 BC. It was introduced to Polynesia, Island Melanesia, and Madagascar in prehistoric times via Austronesian sailors. Sugarcane was an ancient crop of the Austronesian and Papuan people. The young, unexpanded flower head of Saccharum edule ( duruka) is eaten raw, steamed, or toasted, and prepared in various ways in Southeast Asia, such as certain island communities of Indonesia as well as in Oceanic countries like Fiji. In some regions, people use sugarcane reeds to make pens, mats, screens, and thatch. Products derived from fermentation of sugar include falernum, rum, and cachaça. It is consumed directly in confectionery, used to sweeten beverages, as a preservative in jams and conserves, as a decorative finish for cakes and pâtisserie, as a raw material in the food industry, or fermented to produce ethanol. Sucrose (table sugar) is extracted from sugarcane in specialized mill factories. All sugarcane species can interbreed, and the major commercial cultivars are complex hybrids. About 70% of the sugar produced comes from Saccharum officinarum and its hybrids. Sugarcane accounts for 79% of sugar produced globally (most of the rest is made from sugar beets). Grown in tropical and subtropical regions, sugarcane is the world's largest crop by production quantity, totaling 1.9 billion tonnes in 2020, with Brazil accounting for 40% of the world total. The plant is also grown for biofuel production, especially in Brazil, as the canes can be used directly to produce ethyl alcohol ( ethanol). It is native to the warm temperate and tropical regions of India, Southeast Asia, and New Guinea. Sugarcanes belong to the grass family, Poaceae, an economically important flowering plant family that includes maize, wheat, rice, and sorghum, and many forage crops. The plants are 2–6 m (6–20 ft) tall with stout, jointed, fibrous stalks that are rich in sucrose, which accumulates in the stalk internodes. Sugarcane or sugar cane is a species of (often hybrid) tall, perennial grass (in the genus Saccharum, tribe Andropogoneae) that is used for sugar production.
